You see, beginning with the upcoming Ubuntu 25.10, the popular Linux distribution will begin the process of ditching the classic sudo tool in favor of a modern reimagining called sudo-rs. This change is more than a simple code swap -- it’s a sea change in how privilege escalation is handled on Linux, with a clear focus on security and long-term sustainability.

So what exactly is sudo-rs? Well, as the name implies, it’s a new implementation of the familiar sudo command, but this version is written entirely in Rust -- a programming language known for its strict memory safety and reliability. If you’re worried about compatibility, don’t panic; sudo-rs is designed as a drop-in replacement for the original. For most users, it will just work.

Whenever Microsoft rolls out new Windows 11 builds for Insiders in the Dev and/or Canary channels you can never be sure what you’re going to get. Sometimes new features are introduced, other times it’s more about fixing bugs and making general improvements.

Build 26052, for both the Canary and Dev Channels, sees Insiders being moved from 23000 series builds to 26000 series ones. Insiders on both of those two channels will, for a short while, receive the same builds, but it’s only a temporary move.

A serious vulnerability was recently discovered in the sudo tool which could be used to gain root access on Linux-based systems. It soon transpired that the very same issue also affects macOS.

The security vulnerability -- known as Baron Samedit and tracked as CVE-2021-3156 -- is a years-old heap-based buffer overflow bug, and Apple has now issued a patch that fixes the problem for users of Big Sur, Catalina and Mojave flavors of macOS.

Security researchers have revealed details of a vulnerability in Sudo that could be exploited by an attacker to gain root privileges on a wide range of Linux-based systems.

News of the security flaw was shared by Qualys, and it has been described as "perhaps the most significant sudo vulnerability in recent memory". Worryingly, the heap-based buffer overflow bug has existed for almost a decade. It is known as Baron Samedit, tracked as CVE-2021-3156, and affects various versions of Sudo.
